5Watt Digital Optical Rpeater System 37dBm Digital Optical Tri band 900/1800/2100MHz Amplifier DAS Repeater
Distributed Antennas System (DAS) is still the most effective and reliable system that provides in-building wireless coverage and capacity. Indoor wireless connectivity is critical as people spend most of their time either at home, inside office or enterprise locations. In today’s scenario, wireless networks must carry not only voice traffic, but large volumes of data traffic due to proliferation of smart phones and devices. Therefore, DAS system design has become increasingly complex to meet such demand and high SNIR is required in order to achieve high throughput.
2. Digital Signal Processor (DSP): Performs signal regeneration, error correction, clock recovery, and noise reduction.
3. Electrical-to-Optical (E/O) Converter: Re-transmits the regenerated digital signal as amplified optical pulses.
